A severe weather warning remains in place for parts of South Australia, as Adelaide had its wettest February day since 1974.

Emergency services on Friday are responding to dozens of call-outs, as flooded roads and fallen trees cause chaos to drivers and residents in the city.

SES state duty officer Graeme Wynwood has warned drivers to take care.

“Following a long period of very dry weather, the roads are extremely slippery so it is imperative that motorists drive to the conditions,” he said.

The Bureau of Meteorology on Thursday issued the severe weather warning for people in the Adelaide Metropolitan, Mount Lofty Ranges, West Coast, Lower Eyre Peninsula, Eastern Eyre Peninsula, Yorke Peninsula, Mid North, Riverland, Murraylands, North West Pastoral and parts of the Flinders districts.
